Akbank Denied My Credit Card Limit Increase Despite Following Their Instructions

I applied for an Akbank credit card to enroll my child in school, and when it arrived, it had a limit of ₺10,000. I requested a limit increase, but they refused and told me to lower the limits of my other bank cards. I closed a card worth ₺297,000 and reduced the limit of my ₺53,000 card to ₺15,000, yet they still refuse to increase my limit. Despite following their instructions, they keep giving vague responses and unnecessary delays. I have been a responsible cardholder, and my financial history proves my ability to manage a higher limit. My child's early registration opportunity is about to end, and I urgently need this matter resolved. I expect your understanding and request that my transactions be expedited to prevent significant hardship.
